WINDMILL AND PUMP ROD CONNECTION.-

Patented Mar. 21, 18 16.

Application filed May 8, 1915. Serial No. 26,885.

To all whom it may concern: 1

Be it known that I, HERBERT H. CHAPIN, a citizen of the United States,residing at Driscoll, in the county of Burleigh and State of NorthDakota, have invented certain new and useful Improvements in Windmilland Pump .Rod Connections, of which 1 the following is a specification,reference being had to the accompanying drawings.

This invention comprehends certain new and useful, improvements inwindmill and pump'rod connections, and has for its pri mary object adurable and efficient construction of device of. this character wherebythe application of a pump jack or pump handle to the device .willautomatically disconnect the pump rod from the windmill rod so that thepump maybe freely operated by hand or by the jack, andv whereby, whenthe pump handle or jack is disconnected, the pump rod and windmill rodwill beautomatically coupled together.- And the invention also aims togenerally improve devices of this class so as to render them more usefuland commercially desirable.

{With the above and other objects in view, as will more fullyappear asthe description proceeds, the invention consists in certainconstructions,. arrangements and combinations of the, parts that Ishall-hereinafter more fully describe and claim; w

i For a fullunderstanding of the invention, reference is to be had tothe following description and accompanying drawing, in whichi Y Figure 1is a side elevation of a pump rod connection and pump rod operatingmeans made in accordance with my invention; Fig.

2 is a similar view to Fig. 1, but on a larger scale and showing theparts in section; Fig. 3 is a front view of the connection between thetrip device and the pump rod, the pump rod guide and the handle being insection: Fig. 4-;isa fragmentary front elevation of the lower end of thewindmill rod andthe coupling 9 attached thereto.

Corresponding and like parts are referred to in the followingdescription and desig.

connected a trip device 2, said trip device in the present embodiment ofthe invention, comprising two longitudinally disposed bars 3 that aremounted 011 opposite sides of the pump rod 1 and that are pivotallyconnected thereto intermediate of their ends, as indicated at 4. Thetrip device 2 also comprises a back brace, or transverse bar 5 whichconnects the two longitudinal bars together near their lower ends and atransversely extending rod 6 connecting the longitudinal bars togetherat or near their upper ends, said rod being designed to enter a slot 7formed in the pump rod 1 near the upper end thereof and also in slots 8that are formed in the lower end of a coupling 9 designed to be securedby bolts or the like to the lower end of the ordinary wooden windmillrod 10.

Secured to the pump rod 1 is a spring 11, said spring being held atvarying and required degrees of tension against one edge of the pump rod1 by means of a tensioning device 12. Preferably the free end of thespring 11 is curled or curved slightly away from the adjoining edge ofthe pump rod.

13 designates thepump handle. This is 2 forced back of the spring 11 anddown between the same and the adjoining edge of the pump rod 1 so as tobe finally received in a recess 15 formed in said edge, as indicated inthe drawing. Coiled springs 16 are disposed on opposite sides of thepump rod and connected to the longitudinal bars 3 of the trip device 2,said springs exerting a tension on the trip device so as to move thesame in a direction to bring the lower ends of the bars 3 into registrywith the recess 15 and the rod 6 into the recesses 7 and 8 when the sameregister, to operatively connect the pump rod and windmill rod together.

, From the foregoing description in connection with the accompanyingdrawing, the operation of my improved wlndmill rod and pump rodconnection will be apparent. In the practical use of the device, when 1tis desired to pump by hand, the handle 13 is manipulated to bring thepin 14 back of the spring 11 and into the recess 15, this operationserving to cause the forked extremities of the handle 13 to ride uponthe longitudinally disposed cams 17 formed on or secured to the lowerends of the bars 3, or formed by the lower edges of said barsthemselves, whereby the trip device will be automatically tilted tocarry the rod 6 out of the slots 7 and 8 and thus disconnect the pumprod from the windmill rod to allow of the free operation of the pump byhand. Whenever it is desired to again connect the pump rod to thewindmill rod, it is only necessary to pull back slightly on thepumphandle to move the pin 14 out'of the recess 15'whereupon the springs 16will be permitted to act and just as soon as the windmill rod in itssubsequent upward movement brings its recess 8 into registry with therecess 7,'the rods -6 will enter said registering recesses and thewindmill rod and the pump rod will thus be automatically coupledtogether. a

' In order to detachably connect the pump rod to a pump jack operated byan engine, and to automatically disconnect the pump rod from thecoupling 9 at the time that the connection between the pump jack andpump rod is made, I may form the pump rod 1 above the pivot bolt 4 withthe recess 18 which is normally closed by the upwardly 7 extending fiatspring 19 which is outwardly curved at its upper end in the same manneras the spring 11 heretofore referred to. The pump jack is designatedgenerally 20, only a portion of the pump jack being-shown. This pumpjack is preferably bifurcated and formed with the transversely extendingbolt or rod 21, which. when the end of the pump jack is depressed,engages behind the spring 19 and in the recess 18. Upon the downwardmovement of the pump jack 20 so as to carry 7 thebolt 21 into engagementwith the recess 18; the rounded end of the pump jack will forcethe-upper end of the trip'device 2 outward, thus disconnecting the bolt6 from its connection with the coupling 9 and thus disfionnecting thepump rod from the wind m1 V I preferably mount upon the rod 1 below thepivot bolt 4 the spring 22. This spring is a square coil spring and isfastened to the pump rod at'its upper end. The object of this spring isto hold the pump rod up about one-half an inch at the lowest point. Thelower end of this spring upon a downward movement of the pump rodengages the top of the pump rodguide 23. Therefore, in making connectionwith the pump ]21Ck and pump rod the pump rod has a chance to give orsprlng, and this lessens the wear and jolt of the pump rod.

While the accompanying drawing illustrates what I believe to be thepreferred embodiment of the invention, it is to be understood that theinvention is not limited thereto, but that various changes may be madein the construction, arrangement and proportions of the parts withoutdeparting from the scope of the invention as defined in the appendedclaims;

What is claimed is 1. The combination with a windmill rod and pump rod,each having a Sl0t,'0f a trip device comprising bars arranged upon 'opposite sides of the pump rod and pivotally connected intermediate oftheir ends, and a cross rod adapted to enter the slot of the windmillrod, theloweri endsof the barsbeing adapted: to, extend over .the pumprod slot, a lever provided with a pin receivable in saidpump rodslot'fortenga'gement was said bars, whereby theft rip device will be Imoved in a directionpto} carry the cross rod out of the windmillrod'slot, and means tending to move said trip device'in the op: positedirection. n

V 2. The comb nat onwith a windmill rod and a pump rod, of a trip deviceembody ing bars pivotally connected intermediate of their endson thesides of the pump rod, and a cross rod connected tosaid bars near theupper end of the latter andlengageable with the pump rod to connect thetrip device thereto, aspring carried by the pump rod, a lever designedtoengage with said. spring and arranged, upon such engagement; to alsoengage the barsatthe lower endof the latter, whereby the trip devicewill be forced in avdirection to disconnect the cross rod from thewindmill red.
